PATENT LOUIS A. CORNELIUS, OF GRAND RAPIDS, MICHIGAN.

SEWER-PIPE CLEANER.

Application filed September 1, 1923.

To all whom it may concern.

. Be it known that I, LOUIS A. CORNELIUS, a citizen of the United States, residing at Grand Rapids, in the county of Kent and State of Michigan, have invented new and useful Improvements in Sewer-Pipe Cleaners, of which the following is a specification.

The present invention relates to sewer-pipe cleaners, and its object is to provide a device of that character which shall be of vary strong although economical construction; and further, to provide such a device having a turnably mounted globose cleaning head provided with helically disposed flutes on its outer surface; and further, to provide improved means for assembling the parts of such a device; and further, to provide improved means whereby the cleaning head of the device may be mounted on its propelling rod turnably about the rods longitudinal axis and also swingably in planes parallel therewith.

This and any other objects hereinafter appearing are attained by, and the invention finds preferable embodiment in, the structure hereinafter particularly described in the body of this specification and illustrated by the accompanying drawings, in which:

Figure 1 is an axially-sectional view of the globose cleaning head of my device taken on line 11 of Figure 3, and showing its propelling rod Figure 2 shows a modified form of the de vice, illustrating the globose head in axial section and the hollow retaining member partially in the same section;

Figure 3 is a front end View of either of said forms of the device;

Figure 4: is a side view of the modified form thereof seen in Figure 2; and

Figure 5 is a transverse sectional view of the cleaning head, taken on line 55 of Figures 2 and 4:.

My device has a hollow cleaning head 1 or 1 which is globose in form, thus providing a construction which is strongest and most resistive to strains and thrusts exerted from the outside. This head is mounted on the forward end of the devices propelling rod 2, a rearwardly extending continuation 3 thereof, in form a fiat metal strip, being secured thereto at 4. This cleaning head has helically disposed flutes 5 on its outer surface, winding in the same direction, and preferably wedge-shaped in cross section as seen Serial No. 660,479.

in Figure 5. These flutes increase rearwardly in height and width and, as shown in Figure 4;, have blunt rear ends 6.

The cleaning head is mounted on the propelling rod turnably about the longitudinal axis thereof, as shown in Figures 1 and 2, and may be also swingable on said rod in planes in which said axis lies, as shown in Figure 2.

In the simpler form of the device shown in Figure l the cleaning head 1 is secured to the propelling rod by any suitable means, as by the screw 7 extending through the wall of the globose head and threaded in the end of the rod; or in the modified form shown in Figures 2, 4t, and 5, the cleaning head has an internally-spherically formed bearing 8 in which the spherically formed forward end 9 of the rod fittingly bears, in the manner of a ball and socket joint, as seen in Figure 2. In this view, the cleaning head has a rear opening 10, in which is threaded a hollow member 11 containing in its bore 16 the shank 12 of the rod loosely enough to permit the swing movement of the head in planes in which the longitudinal axis of the rod lies. The inner end 13 of this member 11 engages the spherically formed forward end 9 of the rod, thus holding the parts in assembled position when the member 11 is screwed into the cleaning heads opening 10.

It will be seen that as the cleaning head is pushed through a sewer pipe or the like by the propelling rod, its body portion and its flutes dislodge the accumulation of dirt, etc., from the pipes interior, the flutes imparting a rotary movement to the head about the rods axis, and the loose connection of the member 11 with the shank 12 of the rod permitting the swinging movement of the cleaning head described above. As the. rod is retracted, the blunt rear ends 6 of the flutes assist in dislodging and removing such dirt, etc.

It will also be seen that this cleaning head, being globose in form, is peculiarly well capable of resisting breaking strains or thrusts to which the device maybe subjected in practice.

I claim:

1. In a device of the character described: a propelling rod having a spherically formed forward end; a hollow cleaning head containing said end and having an internall v spherically formed bearing in which said end fittingly beacugand having helieally dis? posed flutes-0n its outer surface.

2. In a device of the character described;

a propelling rod having a sphericallyformed forward end and" a shank of rethreaded in said opening, loosely holding the shank'iof the rod, and engaging its forward end tohold the parts in assembled position.

In testimony whereofI have hereunto set my hand at Grand Rapids, Michigan, this 23rd day of August, 1923.

LOUIS A. CORNELIUS.
